21 MPG combined won’t win any fuel efficiency awards, but it’s perfectly acceptable for the 2022 BMW X7 xDrive40i. This isn’t a vehicle purchased by penny-pinchers; it’s a statement of success, a family hauler that prioritizes luxury, space, and a certain image. Buyers accept the X7’s thirst because it delivers an unmatched blend of premium materials, refined performance, and three rows of adult-friendly seating. They are willing to pay a premium at the pump to enjoy the prestige and capability this large SUV provides.

City and highway performance

The 2022 X7 xDrive40i achieves 19 MPG in the city and 24 MPG on the highway. The city figure reflects the reality of moving a vehicle weighing over 5,300 pounds through stop-and-go traffic. The eight-speed automatic transmission tries its best by quickly upshifting to the highest gear possible, but the sheer mass always factors into the equation. The highway MPG demonstrates the efficiency of the turbocharged inline-six at a steady cruise. The engine loafs along, and the aerodynamic shape of the X7, relatively good for its size class, helps to improve gas mileage on longer trips.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 BMW X7 xDrive40i to be $2,750. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. The calculation also uses the national average fuel price from the time of testing. Note that if you drive more aggressively, or experience primarily city driving, this cost will be higher. Rising fuel prices will increase this annual figure, too. It’s a useful benchmark, but your individual experience will likely vary.

Real-world expectations

While the EPA numbers are a solid baseline, it’s important to understand what you might realistically see in everyday driving. Many X7 owners report numbers close to the official estimates, and exceeding the 24 MPG highway figure is certainly possible if you maintain a consistent speed and avoid hard acceleration. On the other hand, consistent use of the X7’s power or frequent short trips in cold weather will reduce fuel economy. Drivers who study all Bmw fuel economy data know how the manufacturer’s own “MPG surprise” often plays out. The X7 MPG across all years offers even more context to prospective buyers.

How it compares

The X7 xDrive40i’s fuel economy lands it in the middle of its competitive set. The Mercedes-Benz GLS 450, another popular choice, achieves a nearly identical 20 MPG combined. The Volvo XC90 B6 manages a slightly better 22 MPG combined, but it lacks the X7’s road presence and outright engine smoothness. The Land Rover Range Rover Sport, while also offering a luxurious experience, comes in lower at around 19 MPG combined with its base engine. For buyers considering the X7, fuel economy is often a secondary concern compared to factors like brand image, comfort, and space, but a few MPG here or there can influence a final decision.

Tips to maximize efficiency

Use the X7’s driving modes. Select “Eco Pro” to optimize throttle response, transmission mapping, and climate control for maximum fuel efficiency. This mode softens acceleration and encourages earlier upshifts. The X7 is capable, but aggressive driving significantly hurts fuel economy.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and maintain the levels specified on the door jamb sticker.

Lighten your load. Removing unnecessary weight from the vehicle improves fuel economy. Clear out any items in the cargo area that you don’t need. The less weight the engine has to haul around, the better.

Use cruise control on the highway. Maintaining a consistent speed avoids unnecessary acceleration and deceleration, which can improve fuel economy on long journeys. Be mindful of traffic conditions and adjust cruise control accordingly.
